[osg-users] Visual Studio 2015 3rd_party

[Sebastian Messerschmidt]

Hi folks,

Since I needed to use VS2015 for a project I built some of the 3rd party 
dependencies for VS2015 for x64.
Is there some spot where can put them? I know that AlphaPixel is/was 
hosting 3rd party, so maybe we can put them there?


Namely I built:
libpng(1618)
libjpeg   (sr6)
zlib(127)
freetype   (ft261)
curl(currently unknown version)

Cheers
Sebastian

[osg-users] the new glTF format by the Kronos Group

[Christian Buchner]

Hi all,

The Khronos group has published a specification for a data exchange and
transmission format for 3D objects and scenes, it appears

https://github.com/KhronosGroup/glTF

I think the OpenScenegraph community might be a interesting in implementing
a a file format plugin, or even come up with a standaloner viewer for this
format.

So far it is hard to tell if this format will be widely adopted. But having
support in OSG from an early point in time could either make OSG more
popular, or glTF...  ;)

Re: [osg-users] Cameras with same target and different near/far

[Riccardo Corsi]

Hi all,

sorry to revamp again my own thread, I'd just like to understand if there's
something I'm missing or if the issue I'm facing is an expected behavior.

So simplify even further my question, I sum it up as follows:
I want to render a scene from within a car. I want to use 2 different
cameras, one for the outside world, and one for the car internals, to
optimize near/far ratio for each of them.
I attach the outside scene under the main camera.
Then I have a camera setup as follows to render the car internals.

   osg::Camera* carCam = new osg::Camera;
   // draw subgraph after main camera
   carCam->setRenderOrder(osg::Camera::POST_RENDER, 1);
   // clear depth only
   carCam->setClearMask(GL_DEPTH_BUFFER_BIT);
   // force near/far values for the car camera

 carCam->setComputeNearFarMode(osg::CullSettings::DO_NOT_COMPUTE_NEAR_FAR);
   carCam->setProjectionMatrixAsPerspective(fov, ar, 0.1, 10);
   // render the user vehicle
   carCam->addChild(carInternalModel);

Now:
- if I add the car camera as viewer's slave, everything works as expected,
near/far is fixed and independent from the main camera
- if I place the car camera in scene, cull settings are overwritten, and
near/far is inherited from the main camera no matter what

Is this the expected behavior?
Thank you,
Ricky

Interesting, I wasn't aware of something like this being in the works.
It could be useful to support, indeed. If someone is building a new
application, this could potentially save them some work, especially if
there will be tooling available.

On the other hand, I don't see much potential for this as an
interoperability format because I don't see major game/3D engine
vendors abandoning their proprietary "baked" asset for this. There is
 too much investment in their existing tooling already and a vendor
lock-in is a major factor in their interest too. E.g. Unity wouldn't
want to make it easier for their paying customers to jump ship to
Unreal (or vice versa). The same for the various asset stores these
companies are running - vendor lock-in is a major advantage there,
because they get to be the gatekeeper and collect toll.

[Chris Hanson]

I could probably crank out a glTF loader in short work if anybody was
interested. I haven't had any clients come forth demanding one yet, but it
may happen. We'll see. Can't be any more complicated than COLLADA! ;)

Hi Chris,

can you contact me via email, so can discuss on the details?

Cheers

Yeah, I'd be up for hosting them.

We're working towards getting our own in-house build system up to 
modern compilers shortly.

Re: [osg-users] INVALID_OPERATION with compressed textures with mipmaps in OSG 3.4.0

[Bradley Anderegg]

Hi,

I can confirm I am seeing this on Windows 7 x64, in addition, I am also seeing 
an occasional driver crash.

Typically after running for about 4 or 5 hours, the video driver will shutdown 
and the OS pops up a notification that says it is has been restarted.  The OS 
recovers but the application crashes on the call to 
releaseContextImplementation() line 2081 in GraphicsWindowWin32.cpp.

I'm not yet sure if these are related.


Thank you!

Cheers,
Bradley

Well, considering it is a part binary format, I wouldn't underestimate
it :) It could be easily a similarly complex mess, only in a different
way.
